LIFTING-J'ACK.

Specification of Letters Patent.

Patented Nov. 6, 1917..

Application led May 29. 1917. Serial N o. 171,664.

To all whom t may concern:

Be it known that I,- WILLIAM PAGELnR, a citizen of the United States, residing at Gladbrook, in the county of Tama and State of Iowa, have invented new and useful Improvements in Liftinfr-Jacks, of which the following is a speci cation.

This invention is a lifting device or jack of the type commonly employed in connection vwith motor or other vehicles to sustain the weight thereof during repairs, although it is not limited in this particular.

One of the objects of the invention is to produce a device of the character referred to, which may be permanently attached to the axle of a vehicle, and means coperating therewith by which the weight of the vehicle may be sustained and lifted. A further object is to produce a device-of this character which may be readily adjusted to axles of di'erent sizes. A further object is to provide a jack having means whereby it may be operated without causing the operator to stoop or assume awkward positions.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing Figure 1 is a side elevation of a jack constructed in accordance with the invention. Fig. 2 is a top view thereof. Fi 3 is a section on the line 3-3, Fig. 1. Fig. 4 is a section on the line 4 4, Fig. 2. Fig. 5 is a section on the line 5`-5 Fig. 1.

Referring to the drawing, 10 designates one end plate of a box or casing, and 11 a corresponding end plate, the plate 10 being provided with top and bottom plates 12, to which the side plate 11 is attached, thereby producing a rectangular frame-like casing closed by suitable side plates, as shown. Rigidly secured to the end plate 11, at'the lower end thereof, is a clamp bar or jaw 13, and adjustably mounted with respect to jaw 13, is a slidable jaw 14, supported in any desired manner. As illustrated, the jaw 14 is provided with a threaded 1u 15, which extends through a longitudina ly disposed slot 16, formed in the end plate 11, a nut 17, working on said lug, servlng to maintain said jaw 14 in operative relation with said side plate. The adjustment of jaw 14 is effected by means of an adjusting rod 18, passed through the jaws 13 and 14, and held this manner the boxor against rotation in suitable manner, a nut 19, working on said rod, serving to rigidly clamp the jaw 14 against an axle or the like, indicated in dotted lines, Fig. 1. In

casing may be securely attached to the axle of a vehicle so as to become thereof.

The top and bottom plates l2 are provided with alined notches 20, which coperate with the inner face of the end plate 11, to form guides for the shank 21, of the standard 22, of the jack. Said shank is provided with rack teeth 23, which mesh with a pinion 24, mounted in suitable bearings in the box or casing, and said pinion is attached to or formed integral with a worm wheel 25, which meshes with a worm shaft 26, suitpractically a permanent part ably supported, said shaft having a squared l end 27. In order that the shaft 26 may be conveniently rotated, I provide a collapsible handle comprising two telescoping sections 28 and 29, preferably of angular cross section to prevent relative rotation, the member 28 having a socket to receive the squared end 27. The outer end of the section 29, is provided with a socket to receive the angular end of a crank member 30, by means of which the handle may be conveniently rotated.

In operation, the jaws 13 and 14 are preferably clamped to a vehicle axle, whereby the entire jack, except the handle, is carried by said axle. The handle being collapsible may be conveniently stored in a tool box carried by the vehicle. When it is desired to utilize the jack, the sections of the handle are extended, and the handle is then engaged with the shaft, and the latter ro- 'tated to lower the standard 22, until it engages the ground or other surface upon which the vehicle is resting. Continuous rotation of the shaft, after the standard has engaged the ground, will lift the vehicle, in a manner well understood in the art. When the jack is no longer needed, reverse rotation of the handle will effect lowering of the vehicle and eventual lifting of the'shank out of contact with the ground, whereupon the handle may be disengaged and folded up to be placed in the tool box.

Having thus explained the nature of the invention, and described an operative manner of constructing and using the same, although without attempting to set forth all S23 iWa/Jiaeea ing jaw rigidly attached to said end Wall, an adjustable clamping jaw having a portion guided by said slot, means :for applying clamping pressure to said jaws, a jack stand- A ard guided by said casing, and means for moving said standard.

ln testimony whereof ll have hereunto set 20 my hand.
